Homemade Kumquat Marmalade

1 . Stage

Inspect four 8-ounce jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until needed. Wash new, unused lids and rings in warm soapy water.

2 . Stage

Rinse kumquats; cut in half and remove seeds. Place in a food processor and process until coarsely chopped.

3 . Stage

Combine kumquats and water in a saucepan. Stir in pectin and bring to a full rolling boil over high heat, stirring constantly. Stir in sugar and vanilla; return to a full rolling boil. Boil and stir 1 minute.

4 . Stage

Remove from heat; skim off foam. Ladle hot mixture into hot, sterilized jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.

5 . Stage

Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 10 minutes.

6 . Stage

Remove the jars from the stockpot and let rest, several inches apart, for 12 to 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.
